Application Meg September 1, ll. Serial No. 48,385.

.irl-o known that L HnNnY'McCoY Noir ins` a citizen ofthe United States, residing at Cincinnati, Ohio. have invented a* new and useful improvement in Gearing, otl which the following is a specification My invention relates to gearing of the rffiss adapted to radial drills or lo other suitable purposes, and the objects 0f m v i npr-nements are to provide a plurality of hangs speed i' indie gears for avoidingr the excessive s eed of the driving pinion on a iarge spint le gear for obtaining highspeed i'orismali drills; to provide a longitudinali)y movable intermediate shaft for detarhably engaging a inion formed thereon with one of the spinde gears; to provide a gradaated snrcession of 4change slpeeds for the spindle through gears of sma 1 ditferenee 1n suceE and to provide .simpleand durable oonstrnrtion and assemblage ot' the coni-ting` members for securing t'arilitf,` of operation and etiicieni'y of action. These objects may be attained in the following desrribed manner, as illustrated in the arroln]anvingV drawings. in wineh Figure 1 is a seetionai ing embodying my improvements, and lig. L a plan with parts in horizontal sef'tion showing the shitting ronneetions.

ln the drawings 1 represents the gear box of a radial drill which may be, adjustahly .mounted on the radial arm (not showniin the usual manner; 2 shift provided with the loose gear 3 formed with a chiteh member 4. The gear 5 splined on the driving shaft is formed with aeollar 8 and with a clutch member T for detachably engaging with the rorresponding mem ,r 1- on gear 3.

The intermediate shaft ti, having the pinion Sl formed thereon, is splined 'inthe sleeves 11 and 12 whirh are journaled in box 1. (iear 13 is secured on sleeve 1I and gear 14 is secured on Sleeve 12 and in continuons engagement With the loose. gear 3 loose gear 15 on shaft 8 is formed with a clutch member 16 and a. eor'iperating elutemember 17 formed with n' eoliar 18 is serured on said shaft and movable' longitudinally therewith. The drill spindle 21 is splined in the sleeve 22 whirh is jonrnaied in a bearing 23 formed in the wall of 'the gear box l. A Small gear :34 is seeured on one end of the'sleeve diagram of a gearth driving' i12 and in rfi'intinuous engagement with the loose gear 1:3 on shaft t5 and a large gear 2.7 secured on the opposite `end oll .said Steeve is adapted to be detaehabl)v engaged by the, pinion f).

Barks 2t; and 2T slidablv mounted in the respertive bearings :5H and 2U are provided with shifting yokes 3] and 32 in movable engagement with the respef-tiwrollnrs t3 and 1H. sieeve Ii?, jonrnnled in a fixed bearing 2H is. provided with a hand lever fifi and ,formed with a segmental gear "M' in engagement with the rai-k :ft for shitting' the gear .'5 into or ont of engagement with the gear 1? and also the rlutrh member T siinn'itaneoi|sl therewith ont of' or into engagement with the clntrh member 4 formed on gear Si.

The shaft 3T jonrnaled in .sleeve E?) is provided with a hand lever '58 and also a segmental gear 39 in engagement with the rank 2 for shitting' the c-luteh member 1T with the shaft S longitmlinally whereinY the pinion il may be engaged or disengaged with the large spindle gear 25 and the ('llltrh members 13 and 1? simultaneously disengaged or engaged for driving the Joos gear y15 with the gnu' i and the spindie.

spring artuated detent 111 serves to maintain the shaft F4 under a lvielding pres sure in dil'lerent predetermined adjustments.

In operation. the size of tbe gears with. their respective number of teeth are so formedthat with the shaft 2 driven at a predetermined constant speed and the clutch members 4 and 6 and also 16 and 17 inengagement as shown in Fig. 1 the geur f3 drives the gear 14 with the shaft 8 and the gear 15 drives the spindle. gear :4 with the spindle at an approximate ratio 4to the speed of shift :Z of `l to l. The disengagement of the clutch members 4 and 7 and the engagement of gear 5 ivith gear 13 drives shaft ii. gear 1f. and gear 24 with the spindle at a ratio to thespeed of shaft Q of 1 t0 2. The reingagement of clutch members 1 and T and the disengagement of elntf'h members 113 andl'l' and the engagement of pinion fl with gear 25 serves to drive said gear with the spindle at a speed ratio to that. of shaft 2 of 1 to i.

The disengagement of the chiteh memi and T and also 1G and 17 and the gear 5 in engagement with the gear 13 "and the pinion t) in engagement with the'gear Patented Nov. 14. 1916.
